To all whom it may concern:

Be it known that 1, JOHN E. GRAYBILL, a. citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Making'lncandescent-Lamp -Mounts, of which the following is a s ecification.

My invention relates to machines for manufacturingincandescent lamps and has for its object the provision of a machine whereby the production of the mounts, that is those portionsof the lamps which sup port the lead. and anchor wires, is greatly facilitated.

My invention can be best explained in connection with theaccompan'ying drawings in whi h;

Figure 1 is an elevation of afmachine embodying my invention; Fig; 2 is an enlarged elevation partly insection ofa ortiorf of the apparatus; Fig. 3 is a'n enlarge view in vertical section of the upper portion of the aption partially in section .Of'l'ile ap aratus of Fig. 3 looking from the right of t at figure; Fig. 5 is a plan view of'th'e apparatus of Figs. 3 and 4 looking from line 5-5 in Fig. 3; Fig.

6 is a plan'view of a supporting clamp; Fig. 7 is a plan view of the machine looking from line 77 of Fig. 1; Fig. 8 is a side elevation of a portion of the machine showing. the mannerv of mounting the mount forming clamps. Y

Referring to the drawings, A indicates a base upon vwhich ismounted a post B which post rotatably supports the hub H by means of a roller-bearing R; Extending radially from the hub is a-plurality of arms a, b, c, and (l, which are rigidly secured .to hub H and at their outer ends carry the hubs e, g, and

" Tothe lower end of the shafts is fixed a of them is sufficient.

h. Fixed-to arms a, b, c and d, is t e ring 1' and at each of two olnts, corresponding to successive arms, rol ers k andk are adapted The means. for operating to engage with it. and supporting the two rollers is the same in both cases and therefore a descri tion of one The roller isfixed t'o. shaft s which is journaled in the bearing D which bearing is pivotally supported by pins as q in the boss-E raised upon the base A.

pulley F by means of which'rotation of the shaft 8 is produced. i Bearing upo'nthe up- -against the upper en wise movement of the shaft is prevented.

i 4 is an elevaper end of bearing D is a collar a secured to shaft 8 .to prevent it from sliding downwardly through bearing D. The tension of the belt upon pulleys F if directed toward the center of the machine will be suflicient to throw rollers 7c and k outward but if not so arranged this may beefi'ected by-springs or other means. There is an extension 0 at one side of bearing D which carries at its end the adjusting screw y. This adjusting screw bears upon boss E and regulates the extent of movement of bearing D upon lpins q. Similar a paratus is carried upon eac of the hubs at the extremities of arms a, b, c, and d and therefore a descriptionof one will be a descri tion Of each.

In u'bg is mounted the hollow shaft 0 which at its lower end has secured to it the wheel w and at its u per end is shouldered d of hub 9 so that end- The wheel to is of such a size that its inner edge is somewhat nearer the center of the machine'than the inner side of ring 1'. Vi'here the shaft C emerges fromthe hub g the arms G and G branch off from it. To arm G is secured the bracket I having the two arms a and u .in which the ends of the shaft .9 are rotatably supported. Shaft s carries a.

lurality of reels as r and 1' '12 is a spring or frictionally braking the reels. The arm G divides at its to into the limbs Z and Z closed by means of springs but ich may be o 'ened by pressure upon the fin er iecesf 'aiid f The centers of the clam grips lie in the axial line of the hollow in shaft 0., Slidjably mounted in the hollow of shaft C is theplunger rod p which extends below the lower end of shaftC. The rod 11 hasone shoulder *atj, another at 7" and another at Between the shoulders .7" and j the collar 7c is rod p'lbetween shoulder .j and collar 2 is sleeve-a which carries the, forming clamp arms a and a. which are pivoted to it and to links m andm which 'in turn are pivoted to limb Z of arm G and carry the mount form-- Covering the r ing-fac -es at their u erends'.

upper end of rod 1) IS the cap C having the longitudinally extending holes k and h andfixed to the rod. S lidably mounted. u on between the s oulder 3 and'cap C is the compression sp ing s*. The screw k carried by cap C, extends into a longitudinal slot in rod p and restrains said cap from rotating while permitting its longitudinal movement. The slot is closed at its ends and therefore limits the longitudinal movement also.

Upon the arm G just below the junction of limbs Z and Z is sleeved the bracket or which is adjustable to and from limb Z by means of the thumb screw t which is threaded in limb V. The bracket n carries a block I) having the longitudinally extending holes k and k in line with the holes h and h respectively and inv one side of said block is formed a recess for the reception of dog (2 which dog is pivoted in bracket n and is of such length that it is restrained from as suming a horizontal position by coming into contact with the bottom of the recess or some interposed object. A similar dog (1 is placed in a recess in cap G I Slidably mounted upon the top of block b is the shearing piece 6 which is guided in its movement and secured to said block by the dove tail f as shown in Fig. 4. The piece e is erforated as shown at h and h and pivotal y secured to piece e is the bell crank d which is pivoted to bracket n at p and has pivotally joined to it the rod r which in turn position lies in the The plunger is spring pressed to its u is pivoted to the collar 6 sleeved on rod which collar has a countersunk seat on t e shaft 0 and is adapted to be engaged by shoulder y', and sleeve x. The rod r is made in two sections. which are joined by the reversely threaded sleeve 0 whereby the length of rod r may be adjusted. The arm G is cut away to recei the rod r as shown.

Upon the o ter end of limb l and secured thereto in a suitable manner is the die block 6 having the tapered axially extending holes 7L5 and h in line with holes h and h respectively. Extending from the top of the die block and located'centrally with relation to the holes 7L3 and h is the needle M; in the top of the die block also are formed the recesses q and g Mounted upon the shaft 0 is the bracket 9 for supporting guide pulleys as g and g for guiding the'wires as they are drawn from the reels. In. the rod p is the recess z opening at one side of the rod to receive the wires and extending axially to a point beneath the cap 0. Extending from each of the hubs e, f, g, and h are the pins as p. 1

Mounted upon the base A is the edestal i in which the lunger p is mounte to have longitudinal but not rotative movement.

er limit of travel by means of a s ring 2' w ch at its lower end bears against t e base A and at its upper end against the plunger. Secured to the top of the plunger is a latch Z which when'the plunger is in its uppermost ath of pins p but is moved out of the pat of the pins when the 1 plunger is moved downward against spring die b -wheels w upon the arms 0 and d which by 115 2 by means of a. connecting link I secured to its lower end. Link Z may be operated by means of a treadle T to which it may be secured by a cord as m. The rod R is adapted to reciprocate in a hole in base A so as to be broughtinto and out of contact with the end of rod p and at its lower end rests upon a lever L. -This lever is fulerumed on the base A or its support and has the operating handle H which when pulled outward forces It upward to operate rod 1).

A pedestal 2' supports a gas burner in such position that the flame will be directed to a point just above and to the center of the die block b on one ofthe arms when it is held stationary by the engagement of latch Z and a pin p and a support i supports a burner in similar relation to an adjacent arm.

Having described the various parts of a machine embodying my invention, I will now outline its operation. An operator seated between the arms a and b, when in the position shown in Fig. 7, places in the clamp c of the arm I) a glass mount tube as shown at 90' in Fig. 2 so that there is a short distance between its base and the'top of die block 0 Within the tube r is placed a smaller and longer tubulating tube a which is held by clam c and whichmay rest upon the top of the lbck b Tubem is placed over the needle n Between the tubes ac and a are inserted lead wires m, the ends of which project within the recesses q and The anchor wires m for the filament are in this case shown as two, although they may be of any desired number and are wound u on reels 1" r whence they pass over the guidh pulleys g 9 then through the recess 2 in rod p and emerging from the end of the rod beneath the cap 0, enter the holes Z2 and 7&2 in said ca thence pass through the holes h and h of lockb and revious to the operation of rod p, wires m aving been sheared by the piece e a ainst the block b in the manufacture of t e previous lamp, they terminate near the top of block b and below the shearing piece 6 In the position as shown, the in p on hub g is in engagement with the atch Z and the rollers 7c and 7c bear upon the their engagement therewith hold the rollers 7c and 7c? out of engagement with the ring 1* and secure the'rotation of the shafts C. A downward pull upon the rod Z releases the pin p from latch 6 when the thrust upon the bearing of shaft 0 causes the arms a, b, c, and'd and hub H to which they are secured to turn upon bearing R in this case in the direction of the arrow, in Fig. 7 and after the wheels w upon armsc and d have been carried out of engagement with rollers 7c and is; said rollers engage with ring'r to continue the movement of the arms and 'hub H until the wheels 'w upon arms I) and 0 have come into engagement with the rollers 7r and 7c respectively when the latch Z having been returned to its upper position by the spring z it will en age with pin upon hubf and stop the furt er rotation hub H and its connected arms. The flame proceeding from the ,gas burner u on the standard 1' will now play u on the ower portion of the tubes ac and r, t ese tubes being maintained in rotation, so that" all sides are heated, by means of the engagement of the roller is and wheel w upon arm I). The hub and arms are maintained in this position while the operation of forming the mount upon the arm 0 is being completed and during this operation the tubes of which the mount is formed, upon the arm I) will receive a preliminary heating.

Upon the com letion of the mount upon arm a the latch is again depressed permitting the hub H andits arms to be moved in a manner as before described, until the wheel to upon arm 6 comes into engagement with roller is and the pin p upon the hub e is stopped against latch Z. The rotation of shaft C and the apparatus carried by it, in

a; order that the tubes may be heated evenly as in the preceding position of arm b, is produced in precisely the same manner and when the tubes as and a have been sufficiently softened by the flame laying upon their lower ends the plunger rod p is pressed upwardly by the operator. The first operation of thus actuating the rod is to cause the shoulder j 'to come into engagement with the sleeve 2? and a further movement of the rod actuates the arms a and a to move the upper ends of the form clamps toward the bases of the tubes at and x at a point just above the die block if. This movement being continued, the top of the cap C will come against the base of the block b and at the same time the shoulder y'will come against the bottom of collar e Throughout this movement of the rod the anchor wires have been clutched between dog-(Z and the bottom of the recess in cap C. and hence said wires are unwound from the reels and carried upward by said cap, their upper ends passing successively through holes h, h and h it until when cap CIrests against the base of b the said anchor wires will project a short distance above the .top' of block 6 movement of rod causes the collar e to be lifted and through the agency of rodr the bell crank is turned about the pivot p so that the shearing piece e moves across the block b and thereby shears off the anchor wires. During the movement of the shear ing piece, the cap C remains stationary having reached the upward limit of its move- Further upward .ment and therefore the wires are stationary during the operationof cutting. The upward movement of the shaft necessary to actuate the shearing piece is ermitted by the compression of sprmg s uring the operation of shearing off the anchor Wires the The function of the needle n is to clamps between which screws the mount is" formed. This operation havin been completed the plunger rod 11 is permitted to fall, in so doing it carries with it the cap C- and after an interval of movement the collar k abuts against 1 the sleeve r. Continued downward movement of the rod carries the sleeve 9: with it and thereby opens 'up the mount forming clamps. .At a certain point in its movement the sleeve 11 engages with the collar e and carrying it back into its seat, resets the shearing piece 6 so that its holes 72 and Marc a ain in 'alinement with holes 71. and h in bloc '6 In its downward movement, however, the cap C does not carry with it the anchor wires which are permitted toslip in an upward direction by the dog (1 and are held against slipping in a downward direction by the dog (1 The process of manufacturing the mount upon arm I) is now completed and'the parts are in position for receiving materials for forming a new mount when the old one is removed. The latch Z is now depressed thus permitting the arm I) to move into the position occupied by arm a in the drawing and the arm a takes its place and the apparatus upon it is operated in the same manner as'that outlined in connection witharm b. In the last position of the arm 5 the completed mount is removed from it. The process observed in connection with the manufacture of a mount upon arm I) is followed in connection with each of the arms as they succeed each other.

the closing 11 of the tube :0 throng which the bulb is to e exhausted when the forming clamps are brought together about its base. It is evident that where the bulb'is exhausted fibm some other point than "the base that the supporting clamp -0 tube 00 and needle n maybedis ensed with. v I 1 While I have shown mounts in which tw anchor Wires are emplpyed, it will ,be ob;

of leading inwires may be provided for.

The die block b has its sides cut away near the top at such aniangl'e that the flame impinging against them is deflected upward revent permit 1 and the top." is of less Width than the diameter of the base of the mount tube so that the flame may enter the tube and thus heat its interior-and also the tubulating tube mounted within it. This action is assisted if the base of the mount tube is held a short distance above the top of the die block and the even heating of the tubulating tube will be promoted if it too is held a short distance above the die block. The entrance of the flame into the interior of the mount tube is extremely important in the construction shown as otherwise there is danger that the tubulating tube will not become properly heated.

According to the patent statutes, I have described my invention in connection with an apparatus which I consider tobe its best embo iment, but I desire to have it understood that it may have other embodiments and I do not desire to be limited to the construction shown in the drawings.
